Aer Arann will be back next Summer again on the ORK route, although this time on a Saturday afternoon/evening.
I'm a little disappointed that RE isn't doing more, because with flights now available from ORK to DUB, BHD and GWY, it would seem to have some potential as a hub point - and would be especially attractive to Irish travellers (of whom there are quite a few on the island) given the recent increases in air travel taxes through the UK. The lack of interline services means that the new taxes need to be paid on each flight, so it does add quite a bit to the cost of getting home.
